Allergy and Immunology News of the Day

Health News of the Day is a daily summary made from the selected links I post on Twitter. It is in a bullet points format with links to the original sources which include 350 RSS feeds that produce about 2,500 items per day.

• Regulatory T cells (Tregs) w transcription factor Foxp3 - 'master regulator' population with many levels of complexity. Foxp3 is a key regulator but insufficient and unnecessary to specify all aspects of the T regs lineage. Treg cell diversity: Distinct subphenotypes of Foxp3+ Treg cells are found in different anatomical locations http://bit.ly/3kAVQJ
  
  
• Developmental plasticity of Th17 and Treg cells - these cells are not "locked" into a final product http://bit.ly/JEksS
  
  
• Asthmatic patients have decreased FOXP3 protein expression within their CD4+CD25high Treg cells. Inhaled glucocorticosteroids in asthmatics increase FOXP3 protein expression within the CD4+CD25high T-cell population http://bit.ly/4FLib
  
  
• TLR choreography: Toll-like receptors (TLRs) must be deployed accurately and finely tuned. Tweaking a single amino acid in a TLR-trafficking molecule determined whether the signal was green or red. TLR7 and TLR9 recognize viral nucleic acids—RNA and DNA, respectively—in endolysosomes http://bit.ly/8ANo9
  
  
• IL-23 Promotes the Production of IL-17 by CD8 T Cells in the Absence of IL-12 and Type-I Interferons http://bit.ly/12e2yA
  
  
• Galvanizing allergies - late-phase allergic responses rely on the zinc transporter Znt5. Removing heavy metals, such as zinc, from mast cells disrupts their activation and blunts allergic responses http://bit.ly/113igK
  
  
• Accumulation of CD28 T cells, within the CD8 subset, is one of the most prominent changes associated with aging http://bit.ly/1l0U0
  
  
• CD95 (FAS) and BIM (BCL-2-interacting mediator of cell death) are 2 major regulators of apoptosis in T cell homeostasis http://bit.ly/6qC51
  
  
• NKT cells turn ten - It has been 10 years since the first workshop on natural killer T cells http://bit.ly/KHG5p
  
  
• Antigen presentation: Basophils do it too http://bit.ly/Lee27
  
  
• American Academy of Allergy, Asthma, and Immunology (AAAAI ) is actually blogging on their Facebook fan page: http://bit.ly/88xdh
